Hi Bob. I have one of those. I will post a picture tonight. they are holders to place different grease guns on. The grease guns were stamped with Texaco on them. The bottom one is a single holder for a can of home lubricant. I don't have the grease guns, but do have the holders in mine. My guess is they were an advertising piece to be put in the showrooms. Although I have seen a couple of the grease guns and they lok like they worked, so maybe it was functional as well as advertising. I think there is a picture of one in the Texaco collector's handbook.
